Upon hearing Aver's agreement, Fiona extended her palm and traced a triangular symbol in the air.
She then fixed her gaze on Aver and slowly asked, "Abyss demon Aver, do you consent to become my servant? To follow me through death or decay, through purification or injury."
This was a ritual Fiona had learned after becoming a demon, capable of making other demons her servants.
However, this ritual could only be applied to demons of a lesser bloodline than her own, and Aver fell within this category.
With a resigned look, Aver lowered his head, his voice tinged with reluctance, "I submit to you as my master, great Evil Queen Fiona."
Instantly, a streak of ethereal light flashed across the sky, and a chain-like shadow tightly coiled around Aver.
Moments later, a trident symbol appeared on Aver's forehead, and the look in his eyes gradually changed.
